TRAVELING FRAME FOR SIDE-SHELL RIVETERS.

Specification of Letters Patent.

Patented Oct. 29, 1907'.

Application filed August 14. 1906- Serial No. 330.566

To all whom it may concern:

Be it known that we, Janus Molnrvnn Dosens, S12, and JOHN McINTYRnDOBBIE, citizens of the United States, and residents of the city andcounty of San Francisco, State of California, have invented certain newand useful Improvements in Traveling Frames for Side-Shell Rivcters, ofwhich the following is a specitication.

In the construction of metal ships, the rivets which hold the platestogether are usually driven by pneumatic riveters held in the hands ofthe operator.

Our invention is designed to hold said pneulnatic riveters in thedesired positions and to relieve the operator from the jar and strainincident to holding the same.-

The object of our invention is to rovide new and improved means foroperating a pneumatic riveter on the sides of ships or in other suitableplaces.

Our invention consists in providing in a traveling frame, improved meansfor taking said frame apart and setting it up.

It also consists in providing in a traveling frame, new and improvedmeans for supporting said frame, having in view the aforesaid meansfortaking said frame apart and setting it up.

It also consists in providing means for preventing the jarring oftraveling frames attached to staging caused by persons walking on saidstaging.

It also consists in new and improved means for securing the bottom partof a traveling frame to the staging about a ship.

It also consists in novel details of construction detailed below.

We accomplish our object by the means illustrated in the accompanyingdrawing of which Figure l is a view in elevation of our invention; Fig.2 a detail view showing the means of suspending our device; Fig. 3 adetail view of the T rail and trolley wheel herein described; Fig. i adetail view showing a bracket for securing our device to a ships side;and Fig. 5 a detail view showing one of the staging clamps referred toherein.

Similar numerals of reference refer to similar parts throughout thevarious views.

Proceeding to describe our device, 1, 2, arestanchions of light steeltubing. Slidable over the outer surfaces thereof are boots 3, 4,provided with trolley Wheels 5, (i. Said trolley wheels run on a track'7, of T-iron, secured to the staging 8 about the ship by the stagingclamps 9, shown in Fig. 5 riveted to said T-rail. Boots 3, and 4, areprovided with arms, shown in dotted lines at 10, ll, which slide intothe hollow cross bar i2, and are secured therein by eye-pins 13, and 14.Said stanchions terminate in heads, 15, 1G, a side view whereof is shownin Fig. 2. Said heads are provided with trolleys l7, [8 which roll on apipe l9 suspended from brackets 20, 2], a side view whereof is shown inFig. i. Said brackets are bolted to the ship through the rivet holestherein. Heads 15, iii, (3 rryarnis shown in dotted lines at 22, 23, inFig. 'l and situated as shown at 22 in Fig. 2. Said arms slide into ahollow cross bar 24 and are secured therein by eye-pins 25, 20. Weprovide a pair of sliding arms 27, 28, secured to sleeves 2.), 30,arranged to slide longitudinally along said stanchions. Said arms havefor their function the carrying of the pneumatic rivcter, indicated at 3which they do by providing said rivctcr with arms slidable into arms 27,and 2S. (.ountcrwcights, shown in dotted lincs at 32, and 33, attachedto arms 27, and 28 by flexible wire ropes 34, 35, are provided, whichact to maintain arms 27, and 28, in any position on the stanchions l,and 2 in which they may be placed. The weight of riveting device iscarried by pipe 19 supported by the bracket 20, 22, and is not supportcdby Trail 7. This expedient relieves the staging 8 of the weight of theapparatus, the troileysf), and t5 acting wholly to keep it on the track.Brackets 20 and 21 are placed about Iitl feet apart, which gives acorresponding d istancc through which our device may be movedhorizontally. The distance between the centers of said slanchions isabout three feet. The height of our device is about eight feet from topto bottom, giving a corresponding distance through which said slidingarms 27 and 28 may be moved vertically. By combining the verticalmovements of said sliding arms with the horizontal movements of ourtraveling frame, every point within the area traversed may be covered.

As to the utility of our device, it should be borne in mind that holdingan operating pneumatic rivctcr in the hands of an operator jars his bodyin a very severe manner, frequently producing derangement of bodilyfunctions of a dangerous character. By our device all the jar is borneby the traveling frame. Moreover there is an increase in the speed andaccuracy of riveting.

In operating our device the operator simply pushes the frame into therequired horizontal position and arms 27, and 28 in the requiredvertical position, directing the hammer against each rivet in turn.

By slipping eye-pins l3, i l, 25, 26, the whole device comes apart, andmay be readily moved to a new position of rails and supporting pipe 19.Rails and pipe are readily moved to new positions on the staging and onthe ship by means of brackets 20, 2i, and clamps 9.

Boots 3, and l, arranged as shown take up any jar caused by work-menwalking over the stagingv We claim:

1. In a traveling frame for sidesliell rivcters, means for slidablysupporting a tool-carrier comprising two stunchions each having a headcarrying a grooved roller adapted to run on a hracketdirack. a tiebetween said heads boots adapted to fit loosely over the bottom portionsof said stanchions having grooved wheels adapted to run on a stagetracka tie between said boots, sleeves slidable over said staucliions havinghollow arms adapted to re reive arms from said t0ol-h0lder, andcounter-Weights connected with said sleeves.

2 A traveling frame for side-shell riveters comprising two stanchionseach having a head carrying a grooved roller adapted to run on a brackettrack, means for tying said heads consisting of arms extending therefromhaving eyes, a pipe adapted to receive said arms having eyes registrable with the eyes of-said arms, and eye-bolts adapted to fit saideyes, boots adapted to fit loosely over the bottom portions of saidstanchions carrying grooved Wheels adaptcd to run on a stage-track,means for tying said boots coning; of arms thereon, a pipe, eyes andeye-bolts, sleeves slidable over said stanchions having hollow arms, at00lcarrier having arms adapted to enter said arms, and counierweightsconnected With said sleeves.

In testimony whereof I hereunto sign my name in the presence of twowitnesses.
